Can the water pump housing be removed?

Removing a broken bolt from a water pump on a 2000 Toyota Solara with a 2.2L engine can be a challenging task, but there are a few methods you can try:

1. Use a bolt extractor tool. These specialized tools are designed to grip the broken bolt and allow you to turn it counterclockwise to remove it.
2. Try using penetrating oil to loosen the bolt. Apply the oil to the bolt and let it sit for a few hours or overnight, then try turning the bolt again.
3. If the bolt is stripped or the head is damaged, you may be able to remove it by drilling a hole in the center of the bolt and using a bolt extractor tool or a screw extractor tool to remove the remnants of the bolt.
4. If the bolt is firmly seized in place, you may need to use a more aggressive method such as using a chisel to create a new groove in the bolt head or using a hammer and punch to try and loosen the bolt.

I recommend using caution when attempting any of these methods, as you don't want to cause further damage to the water pump or the engine. If you are not comfortable attempting these repairs, it may be best to seek the assistance of a professional mechanic.
I hope this helps! Let me know if you have any other questions.

I don't have a diagram. Here are the steps.
1) disconnect negative battery wire..
2) remove serpentine belt
3) remove upper heater hose and thermostat housing; leave thermostat in place
4) remove plate from in front of the power steering pump, the lower bolt is one of three of the alternator bolts.
5) remove all 5 bolts from the PS pump bracket - 2 are by the thermostat housing. Remove the bracket.
6) move the PS pump off to the side out of your way.
7) Remove the long bolt from the alternator you can now see. There is one more alternator bolt at the top which will allow you to remove the idler pulley bracket with the serpentine tensioner. This idler bracket and the tensioner bracket are sizeable, so you have to understand the volume of stuff you are removing.
8) Unhook the alternator wire and with some patience, if you have any left, you can squeeze the alternator out.
This procedure assumes you have the ability to do the serpentine belt removal and refitting, and you will need 12mm sockets/wrenches to do the rest. The t-stat housing uses the torx head screws, so you need that as well.

On 1996 VW JETTA,The thermostat is located at the engine end of the lower radiator hose (passenger side). If the car has power-steering, then power steering pump and mounting bracket are to be removed to get to the thermostat housing. The thermostat is at the end of the bottom hose, in the water pump housing. Follow the lower radiator hose to the water pump housing. There are three bolts that are very difficult to navigate around. The thermostat is located behind those bolts.
----------------- Thank you.

Take housing back off and grab the bolt with vice grips if possible to remove. If not you can buy an extractor set and drill and extract or take it to a machine shop and have them remove.

Water pump is driven by timing chain idler and is mounted on the rear of the timing chain housing. Disconnect the neg. battery cable. Drain cooling system. Disconnect oxygen sensor connector.
Remove upper exhaust manifould heat sheild. Remove exhaust manifold brace. Remove lower exhaust manifold heat sheild. Loosen manifold to exhaust manifold spring loaded nuts. Remove radiator outlet pipe to water pump coverbolts. Disconnect exhaust pipe from manifold.
Pull down on the exhaust pipe to disconnect it from exhaust manifold bolts. Disconnect outlet pipe from oil pan and transaxle. If equipped with manual tranaxle, remove exhaust maifold brace. Leave lower radiator hose attached and pull down on radiator out look pipe to disengauge from water pump. Leave outlet pipe hanging.
Lower vehicle. Remove exhaustmanifold to cylinder head nuts. Remove exhaust manifold to cylinder head nuts. Remove manifould. Remove timing chain front cover. Remove timing chain tensioner. Remove bolts bolts securing water pump cover to cylinder block. Remove water pump to timing chain housing nuts. Remove water pump attaching nuts. Remove water pump and cover assembly. Separate componets as necessary.
WHEN INSTALLING WATER PUMP MAKE SURE YOU FOLLOW THE TIGHTENING SEQUENCES THAT AFFECT SEALING. My frist one I messed up and broke the pump so becarful.
Installation
If cover was separated from body during removal, join this componets with a new gasket and hand tighten bolts. Apply bearing grease to splines of water pump drive. Set body and assemble into position.
Install and hand tighten bolts securing cover to cylinder block. Install and hand tighten bolts securing cover to cylinder block. Installand hand tighten nuts securing body to timing chain housing. Lubracate outlet pipe "O" ring with antifreeze. (I use RTV) Connect outlet pipe. Install and hand tighten bolts. Tighten bolts and nuts to specification in the following sequence. I'll ad the torque spec. at the end but this is where if you tighten out of order something will break.
pump assembly to timing chain housing nuts.
pump cover to pump body bolts
pump cover to cylinder block bolts (Bottom Bolt First)
outlet pipe to cover bolts
To complete installation reverse removel procedure.
Torque specs are 19 in. or 26mm all except water pump cover bolts which are 124 in or 14Nm
I never torque the bolts just make sure there done in the right order.

Water Pump - REMOVAL & INSTALLATION
During these procedures, identify all components removed from the engine so that they may be reinstalled in their original positions. If discarding the old components so that new components can be installed, identifying the old items is not necessary.


1.3L and 1.6L Engines

1. Remove the timing belt cover, timing belt, tensioner, plate and spring.
2. Remove the water pump mounting bolts.
3. Remove the one (1.6L MFI engines) or two (1.3L and 1.6L TFI engines) small rubber seals from between the water pump and the oil pump, and the water pump and the cylinder head.
4. If necessary for clearance, remove the oil level dipstick tube retaining bolt from the engine block and the alternator adjusting brace.
   

Fig. 1: Exploded view of the water pump mounting

WARNING Do NOT use a prybar between the water pump housing and the engine block to separate the two components; this can cause scratches and/or gouges, which can prevent proper sealing.

1. Pull the water pump off of the engine block. If the water pump is difficult to remove from the engine block, use a soft-faced mallet to tap the water pump housing until it loosens.
   

Do not disassemble the water pump; if the water pump is damaged or defective, the entire unit is replaced.

1. Thoroughly clean the water pump gasket mating surfaces of old gasket material and corrosion.

To install:

1. Along with a new gasket, install the water pump on the engine block. Tighten the water pump mounting bolts to 88-115 inch lbs. (10-13 Nm).
2. On 1.3L and TFI 1.6L engines, install two new rubber seals: one between the water pump and oil pump, and the other between the water pump and the cylinder head. The MFI 1.6L engines only use one rubber seal, located between the water and oil pumps.

1. If removed, install the alternator adjusting brace and the oil level dipstick retaining bolt.
2. Install the timing belt, tensioner, plate, spring and cover.

Hope helps (remember comment and rated this).

They can get all the parts. They also provide haynes repair manuals, any special tools (probably not required for this vehicle) and any special disassembly instructions.

I hope this helps.

very very difficult i feel for ya. id try a undersize socket and extension use hammer to drive on bolt head or if at all possible vise grips. also attempt a 6 point box end wrench if it will fit. last resort vise grips. if all else fails left handed drill bits and screw extractor

Need to know engine size but usually water pump is directly connected to the lower rad hose. Moe

1. Remove coolant
2. loosen off alternator belt tension
3. loosen off power steering pump tension if applicable
4. Same with AC if needed
   
5. remove fan hub bolts
6. remove belts shared by water pump pulley
   
7. remove hoses from water pump
8. remove heater core hose from water pump
9. remove alternator support bracket bolt thru water pump housing
10. remove power steering bracket support bolt if applicable
11. remove AC bracket support bolts if applicable.
12. Now remove water pump housing to block bolts(remember sequence)
13. using a pry bar or large screw driver, gently pry the water pump until it releases from the block
14. clean all old gasket material from connecting surfaces
15. Place new gasket in place with a little bit of spray tack
16. then re-install water pump and install bolts as they came out(some are longer than others)
17. Re-assemble all parts in reverse order of removal
18. fill system with new coolant
19. start vehicle and test for leaks before driving anywhere(make sure you have a drop pan under the vehicle
20. Let the vehicle come up to operating temperature,,do final check for leaks with Radiator cap on
    
21. If you have access to a cooling system pressure pump and tester, it would be easier to use this tool to test system.
22. Road test vehicle, add fluid if necessary, enjoy driving.!!
